There is a check valve in the system, probably where the hose from the reel attaches to the motorhome, that allows water to flow inward but not outward. It sounds like your check valve has failed. Sometimes they can leak due to debris, but with water "running out" it sound like the check valve has totally failed.
If you could cap the hose, or put a sprayer head, etc on it that you could turn off, your system would work fine until you can get the check valve replaced -- only thing is that your hose would be pressurized along with your plumbing but that should hurt anything as it is always pressurized when you are on shore water.
